| Abstract: | This Paper deals with the pyroxene porphrite massif, which might be of the cryptoexplosion origin. It is suggested that the abundant volatite components of the parent magma and the multiphase tectonic activity of the Hongchunba-Zengjiaba fault should be the internal and external prerequisites of the cryptoexplosion. |
